but even those served to 
help us make improvements.
.ولكنّ حتّى ذلك الفشل ساعدنا على التّحسّن

Pero gracias a ellos,
mejoramos el cohete.
mais ça nous a permis
de l’améliorer.
ma anche quello ci è servito
 per apportare dei miglioramenti.
mas até esses dias serviram
para fazermos melhorias.
но даже из них
мы выносили пользу.
